Black Diamond provided same day service for both my plumbing and electrical problems. Four friendly guys did all the work in a few hours. I am very happy with the outcome.
JUDY - Crystal Lake, IL
I was ver happy with most of the different things Black Diamond fixed except after installing the new water heater, I noticed several holes in the drywall behind the water heater where no one can now repair the wall unless we in hook the water heater, drain it, move it, repair the wall and then reinstall and fill up the water heater......which will cost me more money .....after the $3000.00 I already spent.
Wonderful, proffesional service!
RICHARD Emery - Crystal Lake, IL
Luis had just repaired our guest half bath and installed a new Kohler toilet in the Master Bath and worked quickly and with confidence and we were very pleased with his service...so we asked for him again when we had trouble with our outdoor pool faucet. We feel certain he fixed our problem.
Fantastic & well informed service team!

I was able to schedule an appointment on the day and during the time period I wanted and needed. The Electrician, Rick, arrived within the time period provided. Rick was very friendly and replaced my bathroom light fixture very quickly. It looks great!

Black diamond is my go to for any electrical needs I have. Our tech Rick was awesome and again is why I only use Black Diamond!
Craig - Crystal Lake, IL
We’ve used black diamond for a few years on all hvac needs. We’re always satisfied. This time our tech went above and beyond. Our home humidifier has “needed to be replaced” for a couple years. To me it’s never been worth the $900 fix to replace it. Yesterday the tech was at our home for a prepaid hvac maintenance. He recognized the humidifier wasn’t working and decided to figure out why... after some electrical investigation he found the problem and fixed it. Because of his experience and work ethic he basically saved me $900. I’ve been told by around 5 other techs that it wasn’t working and would cost me $900 to fix it. Tech: Nick C.

Disappointed in not receiving our 5% discount for being club member. Also in the way it was left after the job was finished.
Eric - Crystal Lake, IL
Fixed a leaking outside spigot in 5 F temps, and saved us from a burst pipe in the basement too during the inside inspection. We call Black Diamond every time.
Outstanding Emergency Service
